This experiment has been agreed to remove its flag in
Sep 12 AOMedia Codec WG meeting.
We first soft-enable it until it gets stable.

The provided encoder option "--tune=[cdef-dist | daala-dist]" is turned
off by default, hence there is no change in bd-rate.

Currently the use of the new multi-layer GF group of 16 is guarded by
the macro USE_GF16_MULTI_LAYER, which is turned off. Hence this CL
does not change any of the encoder behavior.

This patch follows the previous refactoring patch, and further reduces
the number of calls made to scan_row_mbmi and scan_col_mbmi by going
through partition blocks instead of mi blocks. This patch doesn't change
bitstream, which was proven by Borg test result.

The baseline decoder speed test on 1080p clip showed that the average
decoder speedup was 1.1%.(fps: 32.626 --> 32.994)

The calls to count_segs appear very different from each other, but
this is really just because of line wrapping (enforced by the
clang-format linter). This patch produces equivalent code but the
results are far easier to read.

This function is given a bsize and an mi array and has to figure out
what partition to use to divide the given bsize in the direction of
the sizes it finds in the mi array. (Since each block size can be
reached by only one sequence of partitions, this can be done
unambiguously)

The previous version was correct, working by looking up entries in the
partition_lookup array. Unfortunately, that lookup isn't quite enough
when CONFIG_EXT_PARTITION_TYPES is true, so it then had to do some
slightly confusing computations to fix things up after the fact.

The new version should be more self-explanatory and doesn't work by
looking things up in a magic array. It looks up the width and height
corresponding to bsize and compares them with the width and height
corresponding to the sb_type at mi_row,mi_col in the mi array. When
CONFIG_EXT_PARTITION_TYPES is false, this is all you need, and the
four corresponding cases can be found by a lookup in an array of 4
elements.

With extended partition types and a sufficiently large block, you have
to do a bit more searching. For example, if bsize is BLOCK_16X16 and
the subsize is BLOCK_8X8, the partition might be PARTITION_SPLIT, but
it might be one of PARTITION_HORZ_A or PARTITION_VERT_A instead. The
new code adds some comments to explain what's going on.

A nice side-effect of rewriting get_partition in this way is that it
lets us completely dispense with the partition_lookup array.

The patch also fixes comments for the A/B extended partitions in
enums.h, which were slightly backwards (a "horizontal split means two
blocks vertically above one another)

By using a combination of a small qmlevel and large qindex,
it is possible for the quantizer 'dqv' to end up > 2^15.
This currently causes dqv to overflow, so widen its type
to avoid that.

Note that this is certainly an extreme case, but not entirely
useless - if using a 32x32 transform, the dequantized value
can be as small as dqv/2, which may still fit in 16 bits.

The code currently pads the decoded frame width and height to a
multiple of 8 luma pixels, but there is a TODO suggesting that
this may be changed to only require a multiple of 4 in future.

But, as per the comments on the linked bug, there are good reasons
to keep the decoded width and height as multiples of 8. So delete
the outdated TODO and instead outline the reasons why the current
behaviour is helpful.

This allows a mask for mrc-tx to be sent in the bitstream for
inter or intra 32x32 transform blocks. The option to send the mask
vs build it from the prediction signal is currently controlled with
a macro. In the future, it is likely the macro will be removed and it
will be possible for a block to select either method. The mask building
functions are still placeholders and will be filled in in a followup.

Propose the coding structure for GF Group of 16 to use the following
multi-layer design:
  1st Layer: Frame 0 and Frame 16 (ALTREF)
  2nd Layer: Frame 8 (ALTREF2)
  3rd Layer: Frame 4 and 12 (ALTREF2)
  4th Layer: Frame 2, 6, 10, and 14 (BWDREF)
  5th Layer: Frame 1, 3, 5, 7, 9, 11, 13, and 15

This CL implements the reference frame update for a GF group of 16
using a look-up table, which is different from the current
implementation. The motivation behind is to try out various GF group
coding structures simply through manipulating the look-up table,
instead of making changes on swapping the reference indexes and
associated flags throughout the codebase.

Since CDEF looks uses the luma direction for chroma, CDEF would have
to change significantly to support formats like 4:2:2.  The limited
use of such formats does not justify the complexity to support this,
so the simple solution is to mandate that the chroma planes aren't
filtered if subsampling_x != subsampling_y.  Most of the visual gain
is in luma, anyway.

This also means that the chroma strengths and chroma skip condition
shall not be sent if subsampling_x != subsampling_y.

When cdef-singlepass is enabled, it is possible to signal the
CDEF parameters in such a way that we end up with unsigned
integer overflow in constrain().

Fix this by i) using signed instead of unsigned values,
and ii) clamping the result to avoid going on to shift
by a negative amount.
